Calcium
High-dose calcium and magnesium compete for absorption when taken simultaneously.
Recommendation: If taking high doses (>500mg each), separate by 2+ hours. Moderate doses can be taken together.
Magnesium Taurate
Mineral ·Moderate evidence ·Reviewed May 2026
Magnesium chelated with taurine, specifically targeted for cardiovascular support.
The bottom line
Evidence rating moderate. Most-documented uses: heart health, blood pressure, arrhythmia support. 12 sources indexed (1996–2025), with 18 interaction records on file.
The science
How it works, mechanistically.
Core mechanism
Combines cardiovascular benefits of both magnesium and taurine. Magnesium regulates cardiac ion channels; taurine stabilizes cell membranes and modulates calcium handling in cardiomyocytes.7,9

Forms
Forms & what to buy.
Ranked by evidence and value.
Glycinate / Bisglycinate Recommended
Highly bioavailable and well tolerated. Chelated form with low laxative effect and strong GI tolerability.
~80% relative bioavailability
Citrate
Good general-purpose oral form with moderate absorption. Well absorbed but can loosen stools at higher doses.
~65% relative bioavailability
Oxide
Very low absorption despite high elemental magnesium content. Poor oral absorption; inexpensive but inefficient for repletion.
~5% relative bioavailability
L-Threonate
Lower elemental content but valued for CNS-focused use. Magnesium L-threonate is marketed for brain penetration; elemental yield is low.
~45% relative bioavailability
Taurate
Moderate absorption with taurine added for cardiovascular support. Chelated form that is usually gentle on the stomach.
~55% relative bioavailability
Malate
Moderate absorption with malic acid support. Often preferred when magnesium is used for daytime energy support.
~55% relative bioavailability
Orotate
Moderate absorption; niche form commonly marketed for heart support. Usually well tolerated but typically more expensive than glycinate or citrate.
~50% relative bioavailability
Chloride / Oil
Absorption is variable and product-dependent. Topical magnesium bypasses some GI intolerance but systemic absorption is inconsistent.

Assumes 200-350 mg elemental magnesium/day. Vendor basis: NOW/iHerb, Vitacost, Amazon marketplace, and practitioner brands; taurate is less commodity-priced than citrate or malate. Updated 2026-05-28.
From food
The same dose, as food.
How much you'd eat to match a supplemental dose.
200-350 mg elemental magnesium
About 1 ounce pumpkin seeds plus spinach, almonds plus black beans, cashews plus whole grains, dark chocolate plus legumes, or avocado with seeds can approach the magnesium target.
Foods provide magnesium and some taurine separately, not magnesium taurate as a salt.

Magnesium and taurine are studied for cardiovascular physiology, but heart-rhythm claims require clinician context.7,9

Magnesium supplementation has small but measurable blood pressure effects in randomized trials; the taurate form is a tolerable cardiovascular-oriented option, although most evidence is magnesium-specific rather than form-specific.1,3

Interactions
Interaction records.
InfoSynergy
Vitamin B6
Vitamin B6 increases intracellular magnesium accumulation. Magnesium is required for B6 activation to its coenzyme form PLP.
Recommendation: Take together for enhanced mutual absorption and utilization.
InfoSynergy
Vitamin D3
Magnesium is essential for vitamin D metabolism. It's required for the enzymes that convert D3 to its active form calcitriol.
Recommendation: Ensure adequate magnesium when supplementing D3. Magnesium deficiency can impair D3 activation.
InfoSynergy
Vitamin B1
Magnesium is required for thiamine (B1) utilization. Magnesium deficiency impairs thiamine-dependent enzyme activity.
Recommendation: Ensure adequate magnesium when supplementing B1 for proper enzymatic function.
InfoSynergy
Ashwagandha
Both promote relaxation and support sleep quality through complementary mechanisms.
Recommendation: Take together in the evening for enhanced sleep and stress support.
InfoSynergy
L-Theanine
L-theanine and magnesium are both studied for relaxation-related markers, but direct combination evidence is limited.
Recommendation: If combining L-theanine with magnesium taurate, keep total supplemental magnesium within 200-350 mg/day elemental magnesium unless clinician-supervised; do not frame the pair as anxiety treatment.
InfoSynergy
Melatonin
Melatonin and magnesium are commonly used in sleep routines, but direct stack evidence and optimal dosing vary.
Recommendation: If combining melatonin with magnesium taurate, keep magnesium within 200-350 mg/day supplemental elemental magnesium unless clinician-supervised and keep melatonin use situational or clinician-guided for persistent insomnia.
InfoSynergy
Apigenin
Both promote relaxation and sleep through GABAergic and glutamate-modulating pathways.
Recommendation: Combine for a gentle, non-habit-forming sleep support stack.
ModerateSynergy
Potassium
Magnesium deficiency causes renal potassium wasting. Correcting magnesium is often necessary before potassium levels can normalize.
Recommendation: If hypokalemic, check magnesium status. Refractory hypokalemia often resolves only when magnesium is also repleted.
ModerateTiming Sensitive
Iron
Magnesium and iron can compete for absorption when taken together. Separate for optimal absorption of both.
Recommendation: Take iron in the morning on an empty stomach. Take magnesium taurate in the evening.
InfoSynergy
Creatine
Magnesium is required for creatine kinase enzyme activity, which phosphorylates creatine to phosphocreatine.
Recommendation: Ensure adequate magnesium when supplementing creatine for optimal ATP buffering.
InfoSynergy
Calcium
At moderate doses, magnesium and calcium work synergistically for bone health and muscle function. Calcium for contraction, magnesium for relaxation.
Recommendation: Aim for 2:1 calcium-to-magnesium ratio. Both are essential for bone density and neuromuscular function.
